  • Accessories
  • Now 25 years in business, Norlab is a specialist supplier of Separation Science & Dissolution Instruments and Accessories, Laboratory Fluid Handling Solutions and more. (norlab.fi)
  • stationary phase
  • The mixture is dissolved in a fluid called the mobile phase, which carries it through a structure holding another material called the stationary phase. (wikipedia.org)
  • The mobile phase moves through the chromatography column (the stationary phase) where the sample interacts with the stationary phase and is separated. (wikipedia.org)
  • Hydrodynamic instruments are often marketed as high-speed or high-performance countercurrent chromatography (HSCCC and HPCCC respectively) instruments which rely on the Archimedes' screw force in a helical coil to retain the stationary phase in the column. (wikipedia.org)
  • Nearly any pair of immiscible solutions can be used in countercurrent chromatography provided that the stationary phase can be successfully retained. (wikipedia.org)
  • chemistry
  • Chromatography technique developed substantially as a result of the work of Archer John Porter Martin and Richard Laurence Millington Synge during the 1940s and 1950s, for which they won the 1952 Nobel Prize in Chemistry. (wikipedia.org)
  • Interchim has now major activity in fine chromatography, fine chemistry and bio-analysis. (wikipedia.org)
  • organic
  • One approach of SFE of metals is by converting charged metal ions into neutral metal chelates using organic chelating agents dissolved in supercritical CO 2 [1- (scribd.com)
  • form
  • Bob Brownlee took the initiative "along with Tom Jupille, Steve Bakalyar, Nelson Cooke, Jerry Higgins and Ron Majors" to form the Bay Area Chromatography Colloquium. (wikipedia.org)
  • compounds
  • Quantification of the extracted metal chelates and organometallic compounds can be achieved by supercritical fluid chromatography (SFC). (scribd.com)
  • It is used to separate one chemical compound or one class of chemical compounds from one or more other chemical compounds to provide significant quantities of the purified or enriched material at a lower cost than could be obtained using simple (batch) chromatography. (wikipedia.org)
  • molecular
  • Starting in the 1970s Smith published peer-reviewed papers on several subjects, including mass spectrometry, ion cyclotron resonance mass spectrometry, ion-molecule reactions, molecular assemblies, and supercritical fluid solutions. (wikipedia.org)
  • water
  • Depending on the level of purity needed, detection of these contaminants can range from simple conductivity (electrolytic) readings to sophisticated instrumentation such as ion chromatography (IC), atomic absorption spectroscopy (AA) and inductively coupled plasma mass spectrometry (ICP-MS). Ultrapure water is treated through multiple steps to meet the quality standards for different users. (wikipedia.org)
